SAR ‘NG O-3’ ‘Insulated-Wagon’

In the late 1970s, trials were conducted into the transportation of pre-cooled palletised fruit on the Avontuur Branch, which required the use of an insulated van. Following a successful trial, all 200 ‘NG OZ-6’ vehicles were rebuilt along with many ‘NG OZ-5s.’ In order to accommodate an international standard pallet of fruit stacked 6 cartons high, the roof was raised by 476mm and the central doors replaced by larger ones, offset to the left. The walls and floor received new insulation and adjustable ventilators were fitted in the ends. The introduction of these vehicles on the Avontuur revolutionised the loading process; where previously individual cartons had to be hand loaded, taking around 35 minutes per wagon, the new vehicles could be loaded in 5 minutes using a forklift. When one considers these export fruit trains could load to 15 wagons and there might be up to 12 a day during the season, this marked an immense improvement in efficiency. Whilst these vehicles were often seen in block trains, photos also show them mixed in on all manner of other workings.
One of the accompanying photos gives a comparative view of the original ‘OZ-5’, compared with a rebuilt ‘O-3’.

Whilst these vehicles are comparatively tall for 16mm Narrow Gauge stock, at 170mm, for comparative purposes they are no taller than the rear headlamp on a Roundhouse Darjeeling B-Class; if built to the instructions supplied.
